An ink-jet printer works by deflecting charged drops of ink by a uniform electric field An ink drop with mass 7.8 x 1010 kg and charge 2.0 x 10-13 C enters the region between two parallel plates with an initial velocity of vy =11 m/s in the x-direction only. Each plate has a length of 1.4 cm. The surface charge density on the plates needs to be µC/m² in order to deflect the ink drop 0.80 mm towards the negative plate.
